the driving mechanism is used for driving the carriage assembly to move towards the tail end of the main frame 1 until the second carriage 22 is separated from the main frame 1, and is also used for driving the first carriage 21 to rotate based on the first rotating mechanism 23 in a state that the second carriage 22 is separated from the main frame 1.

The working principle of the backward-moving overturning self-discharging structure is as follows: in the backward-moving overturning self-unloading structure, a carriage assembly is of a split structure and is formed by combining a first carriage 21 and a second carriage 22, the joint positions of the two carriages are communicated in a normal state, namely the carriage assembly can be used as a normal carriage assembly for loading cargoes, when the carriage assembly is unloaded, a driving mechanism drives the carriage assembly to move to the tail end of a main frame 1 until the second carriage 22 is separated from the main frame 1, the second carriage 22 overturns under the action of gravity and/or external traction based on a second rotating mechanism 24 and downwards overturns one side of the second carriage 22, which is close to the first carriage 21, the cargoes loaded on the second carriage 22 are unloaded to perform preliminary unloading, after the preliminary unloading, the driving mechanism drives the first carriage 21 to overturned based on the first rotating mechanism 23, the head of the first carriage 21 is lifted, and the cargoes are unloaded from one side, which is close to the second carriage 22, when the first carriage 21 is lifted and unloaded, therefore, the second carriage 22 forms a blocking structure when the first carriage 21 is unloaded to a certain extent, so as to prevent materials, ash layers and the like from being lifted, even if the unloading areas are completely unloaded, the unloading areas are completely reset, and the unloading areas are completely driven and the unloading areas are completely; through the application of the backward-moving overturning self-unloading structure, cargoes loaded by the carriage assembly can be separated into secondary unloading, the load of the driving mechanism when the carriage assembly is lifted can be effectively reduced, the first rotating mechanism 23 is approximately located at the tail end of the first carriage 21, the length of the carriage actually lifted is the length of the first carriage 21, so that the lifting height is effectively reduced, the telescopic length of the driving mechanism is further reduced, the requirement of the lifting part of the driving mechanism is effectively reduced, the rollover risk is effectively reduced, the safety performance of the whole vehicle is greatly improved, on the other hand, the lengthening of the length of the carriage assembly can be further realized on the basis of the existing maximum length of the carriage by the backward-moving overturning self-unloading structure, the cargo loading capacity is effectively improved and the safety can be ensured under the condition of reducing the requirement of the driving mechanism.
